Preparation method and spraying process of C40 inorganic coating anti-freezing concrete
The invention discloses a preparation method and a spraying process of C40 inorganic coating anti-freezing concrete. The preparation method comprises the following steps: pouring sand and stones intoraw material bins for pre-homogenization, wherein the pre-homogenization time is 5-10 minutes, and the stirring speed is 5-10 r/min; stirring and mixing the pre-homogenized sand and stones in a forcedstirrer for 2 minutes at the stirring speed of 3-6 r/min; mixing, adding cement, fly ash, a polycarboxylate superplasticizer and water, stirring for 5 minutes, adding an XTHPA environment-friendly high-permeability inorganic crystal waterproofing agent, and stirring for 2 minutes at the stirring speed of 3-6 r/min to obtain a concrete test block; and maintaining the concrete test block in water for 28 days, and spraying an XTHPA environment-friendly high-permeability inorganic crystal waterproofing agent and an XTSS environment-friendly surface sealant. The inorganic coating and the outer inorganic coating are added, so that the waterproof and adhesive properties of the concrete are improved, and the frost resistance and durability of the concrete are improved.
本发明公开了一种C40无机涂层抗冻混凝土制备方法及喷涂工艺。将砂子、石子倒入各自原材料仓进行预均化，预均化的时间为5‑10min，搅拌速度为5‑10r/min；预均化后的砂子、石子放在强制搅拌机内搅拌混合2min，搅拌速度为3‑6r/min；混合后再加入水泥、粉煤灰、聚羧酸减水剂和水搅拌5min，后加入XT‑HPA环保型高渗透无机结晶防水剂搅拌2min，过程的搅拌速度为3‑6r/min，即得混凝土试块；将混凝土试块在水中养护28天，喷涂XT‑HPA环保型高渗透无机结晶防水剂和XT‑SS环保型表面密封剂。本发明加入无机涂层和外涂无机涂层，提高混凝土的防水和粘结性能，提高混凝土的抗冻耐久性。
